Projecting from the disc 36 is a fingerpiece 38 affording means for rotating the disc and also ar ranged to contact with the edges of the bracket and thus limit the rotation of the disc in either direction.

Fixed upon the spindle 26 between the division and front plates 18 and 19 and preferably immediately behind the latter is a flat inctal claw plate 39 which has a pair of teeth or claws -19 l'orlnod upon its edge and arranged diametrically opposite one another.

The oval shaped floating yoke or sleeve 41 surrounds the spindle 26 between the plates 18 and 19 and has a portion of its wall cut away to form a pair oi: shoulders 42 diametrically opposite to one another and with which the teeth 49 of the claw plate 39 engage.

The bolt l slides within a hole l t bored from the edge of the door to meet the aperture 13 at a right angle. The bolt 43 has on its inner end a T-hcad 15 which passes through one of the elongated slots 46 in one of the distance pieces 17 and thence through another elongated slot 1-? in the yoke 4-1; the bolt 41-3 is then given a quarter turn to couple it to the yoke 11. A helical spring 48 is arranged around the reduced portion of the bolt -13 and bears against the distance piece 1'? and the shoulder -13 of the bolt, said spring tending to force the bolt outwardly. A llat Fl-9 is provided on the outer end of the bolt where it passes through a keeper plate so in which is a Dshapcd aperture 51 preventing lhe holt from being turned and released from the yoke 11.

The distance pieces 17 each have an elon' gated hole 17 as hercinbelorc mentioned. and the yoke 41 has an elongated hole at each end to enable the lock to be adjusted for right or left hand fitting as desired. That is to say the bolt may be arranged to project radially from either side of the barrel.

A cover plate 52 may be used so as to give a set oli appearance to the lock when alfixed to a door, and this plate is formed with a slot 52 (registering with the keyhole in the plate 19) which enables it to he fitted after the lock has been otherwise completely fitted.

To facilitate the attachn'ient of the bolt to the yoke ll. the latter is lcn'lporarily held in position by a temporary screw 55 (see Fig. 12) taking into one of the screw threaded holes 58 in the plate 19. The barrel of the lock is inserted into the hole 13 in the door 14, and then the bolt 13 with its coil spring 48 is inserted in the hole 44 in the door stile, the T-head passing through the elongated apertures 16 and 47. The belt is given a quarter turn and the keeper plate 56 secured into position. The temporary screw then extracted, and finally the cover plate 52 is attached.

To enable the lock to be opened from without when it is not set to function as a latch only, but functions as a look, a specially constructed key is required. Such akey is depicted in part of Fig. 1, in Figs. 3 and 4: and in dotted lines in Fig. 9. The key comprises a stem 24 formed with steps or wards and bevelled at its end as at 5st. Shoulders or fins 56 are provided to determine the longitudinal position of the key in the lock which must be such that the wards 53 underlie the ward plates 30 when the key is pushed fully home through the holes registering 23, 22 and 21 in plates 19, 18 and 19 respectively, as shown in Fig. 4. The hole 23 in the outer lamination o'l plate 19 is, as regards its upper portion, made larger than the hole in the inner lamination, and is formed to provide shoulders 57 as clearly shown in Fig. 12. When the key is pushed home the longer of the fins 56 enters the enlarged upper portion of the hole in the outer lamination of plate 19 and abuts against the inner lamination. The shoulders 57 constitute stops limiting the turn ing movement of the key. The key is inserted with the bevel 54; facing upwardly and the wards or steps 53 downwardly as shown in the upper part of Fig.

The effect of the spring 48 not only outwardly presses the bolt 43, but, as the result: of such outward pressure, the yoke 4:1. is pulled laterally and the shoulders thereon hear evenly against the claws 4.0 on plate 39, thus normally holding the spindle 26 so that the waist thereof is in register with the slots 32 in the ward plates 39. Normally the ward-plates are in their lowest positions with the upper slots 32 engaging the waist of the spindle as shown in Fig. 19. The entry of the key in the notches in the lower edges of the warthplates raises the latter, but as the notches 33 are of various depths, some of the ward plates are raised sufficiently to bring their circular apertures 81 into register with the spindle, while others are raised to such an extent that the lower slots 32 engage the waist and prevent the turning of the spindle at this stage. On the key being given a half turn anti-clockwise to the position shown in the lower partof Fig. 3, the wards or steps thereon are brought into position underlying the ward-plates which drop into said steps rospectivcly. The ward-plales, the apertures therein and the wards or steps of the key are so relatively constructed and arranged that when in their co-operative positions the circular apertures 31 in the ward-plates are all in alignment and in register with the ill) spindle so that the latter may. be rotated in either direction, such rotation, by the coaction of the claw plate 39 and yoke 41 retracting the bolt 43 and permitting the door to be opened. The key is now given a halt turn in reverse direction and withdrawn from the lock, the parts of the latter re-assuniing their normal or looking positions.

To enable the spindle to be rotated from inside the door and also, if desired, from the outside withoutusing the key, the catch device is provided. When the disc 36 is turned to its limit in one direction the crank pin is disposed in its lowest position as shown in Fig. 9 and does not have any effect on the ward-plates 30, but when the disc is turned to the other extreme position the crank pin is in its uppermost position and the effect is to raise the ward-plates so that 'their circular apertures 3l are in register with the spindle "26 and the latter may be turned'in either direction. 34 in -the ward-plates respectivelyare so arranged that this effect is obtained, On re turning the disc to the first mentioned posi -tion the ward-plates are treeto return to their locking positions.

What I claim and desire to secure by Letters Patentis: V

1. A look including a barrel portion to fit in a hole bored transversely through a-door, and a bolt movable radially to andfrom the barrel portion and outwardly pressed by a spring, said barrel portion comprising a pair of end plates and an intermediatedivision plate all maintained in spacedparallel relation, a rotatable spindle passing through said end plates and division plate and having bearing in the end" plates, said spindle being fitted at each end with means for rotating it and being cut away on' opposite sides to provide asubstantially rectangular waist portion located between the division plate and one of the end plates,a plurality of ward-plates individually slidable in guides in a plane at right angles to the spindle, each The apertures of said ward-plates havinga clearance aperture (permitting the passage and rotation, of the spindle) and a pair of oppositely 'disposed radial slots extending from the clearance aperture, one of said slots in each plate normally engaging the waist of the spindle to' prevent the latter being rotated until by the operation of an appropriate key the ward-plates are moved to bring their clearanceapertures into alignment and in registerwith the axis of the spindle, a floating yoke about the spindle formed with shoulders and with means 'for connecting the in-' ner end of the'bolt thereto, and, fixed on the spindle a claw. plate having claws co-operat ing with said shoulders to move the yoke and retract the bolt when the spindle is rotated.

, clearance aperture and a pair ofradial slots oppositely disposedand in alignment with the normal angular position of the waist portion oi the spindle, means operated from that end of the barrel portion presented to the inside of the door for moving the ward plates to disengage their radial slots from the waist portion of the spindle, a bolt disposed radially to thespindle, a floating yoke torn'ied with shoulders and with means for attaching to it the inner end of said bolt, and a claw plate fixed onthe spindle and cothe spindle is rotated.
